Water on hands could conduct electricity into your body if there is short circuit in the electrical device.
Different countries have different regulations about electrical inspection.
I think that it is insulation but you might have to check elsewhere to make sure. :D
A flow of electrons is needed to have a current. And there (usually) must be a complete circuit. And you need a voltage to make the current move around your circuit. All tied up in Ohms Law - which I'll leave to you.
An electrical contractor or electrician would definitely be competent to help with that repair. The handyman laws in some states allow a handyman to perform minor repairs such as replacing a circuit breaker. It's a simple process, you just have to make certain that you shut down the power so nobody gets electrocuted. Replacing a circuit breaker is not a minor repair, NFPA 70E - Standard for Electrical Safety in the Workplace as well as the National Electrical Code state that only a qualified person can do electrical work. A qualified person is "One who has skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the hazards involved."
you need an electrical supply and a load. nice and simple.
A switch is used to make or break an electrical circuit.

That is called a short circuit.
A circuit can be classified as a voltage source connected to a load.

The equipment is all connected in series with each other to make a complete electrical circuit.
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum).

No. only flow of current develops electrical field. whereas magnetic field can make current to flow through a closed path. Absolutely YES. I wander how radios and TV works.AnswerYes, it is an electric field that causes current to flow in a circuit.
